3. All of the organic molecules are based on which element?

Ulleksa [173]

Answer:

<h2>Carbon. </h2>

Explanation:

Life is based on carbon; organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.

How might targeting rapidly growing cells explain common chemotherapy side effects such as hair loss and nausea

IrinaVladis [17]

Cancer cells are the cells that divide rapidly than any other cells in the body. The drugs used in chemotherapy work on rapidly dividing cancer cells. Some cells of our body apart from cancer cells also divide rapidly along with the cancer cells such as the cells that line the stomach and the digestive tract. Chemotherapy drugs cannot differentiate the cancer cells and the normal cells so these drugs also attack the normal cells which divide rapidly along with the cancer cells. The drugs also attack the cells that are present in the roots of the hair. So, this results in the hair loss. Hair loss does not occur immediately after the chemotherapy treatment instead it starts after few treatments. The degree of the hair loss after chemotherapy depends on the drug type and process. So when the chemotherapy drugs are used it results in the hair loss and nausea.

Therefore, when chemotherapy drugs attack normal cells including the roots of the hair instead of cancer cells that divide rapidly along with the cancer cells it results in the hair loss and nausea.

At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway

alukav5142 [94]

Answer:

Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

The publications above cited are the following:

il63 [147K]

The committee that advised the Fed on the growth of the money supply and the level of interest rates is "B", the Federal Open Market Committee.
The Federal Open Market Committee is the branch of the Federal Reserve Board that determines USA monetary policy. It consists of twelve members and holds eight meetings a year. The committee reviews current economic and financial conditions to plot the way forward for the Federal monetary policy. It also assesses the risks to its long-term goals of price stability and sustainable economic growth.
